As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
the build fails on m68k with the following diagnostics:
In file included from ./../nat/linux-ptrace.h:28:0,
from linux-low.h:27,
from linux-m68k-low.c:20:
[...]/usr/include/sys/reg.h:26:3: error: expected identifier before numeric constant
PT_D1 = 0,
^
[...]usr/include/sys/reg.h:26:3: error: expected « } » before numeric constant
[...]usr/include/sys/reg.h:26:3: error: expected unqualified-id before numeric constant
In file included from linux-m68k-low.c:27:0:
[...]usr/include/sys/reg.h:99:1: error: expected declaration before « } » token
};
^
Fix this by moving <sys/reg.h> on top of "linux-low.h".

This adds a patch to gdb 7.12 and gdb 8.x, which fixes the build on
noMMU platforms. It is not needed for older versions of gdb, since
it's related to the switch of gdb to C++ in the 7.12 release.
Fixes:
../nat/linux-ptrace.c: In function 'int linux_fork_to_function(gdb_byte*, int (*)(void*))':
../nat/linux-ptrace.c:273:29: error: invalid conversion from 'void*' to 'gdb_byte* {aka unsigned char*}' [-fpermissive]
child_stack = xmalloc (STACK_SIZE * 4);
The patch has already been merged upstream, as of commit
ffce45d2243e5f52f411e314fc4e1a69f431a81f, and will therefore be part
of future gdb releases.

Currently building full gdb for MIPS musl fails because it's trying to
include <sgidefs.h> which is provided by glibc and uClibc, but not by
musl.
However, the kernel headers provide <asm/sgidefs.h> which has the same
definitions, so we can use that one instead.
Backporting a patch that has been sent upstream. Taken from here:

This commit adds a small patch to gdb that fixes the build of gdbserver
on m68k/coldfire:
../nat/linux-ptrace.c: In function 'linux_fork_to_function':
../nat/linux-ptrace.c:282:19: warning: implicit declaration of function 'clone' [-Wimplicit-function-declaration]
child_pid = clone (function, child_stack + STACK_SIZE,
^
../nat/linux-ptrace.c:283:5: error: 'CLONE_VM' undeclared (first use in this function)
CLONE_VM | SIGCHLD, child_stack + STACK_SIZE * 2);
^
../nat/linux-ptrace.c:283:5: note: each undeclared identifier is reported only once for each function it appears in
Thanks to Waldemar for pointing out the patch fixing this issue.

This commit small patches to gdb that fix redefined structures build
problems that occur when building on PowerPC, PowerPC64, PowerPC64le and
SuperH with the musl C library.
The PowerPC(64)(le) patch was taken from the Yocto Project, the SuperH
patch was inspired from the PowerPC patch. The issue has also been
reported upstream to the musl developers:
